Abstract: The present invention relates to a sheet-shaped adhesive and an adhesion method thereof, wherein the sheet-shaped adhesive includes a sheet carrier, a colloid, and isolation films; the sheet carrier has a plurality of non-closed accommodation spaces densely distributed therein; the colloid is coated on the sheet carrier, permeates and fills all the accommodation spaces; and the isolation films seal and wrap the sheet carrier coated with the colloid, so as to solve the problem that the existing adhesive easily causes waste and easily forms air bubbles to cause poor adhesion.

Abstract: The present invention provides a phosphorus-containing compound characterized by being a compound represented by the following structure: the compound is a novel immune cell migration inhibitor. The compound has good hydrophilicity and can be developed into eye drops. The compound has a strong inhibitory ability to immune cell migration and can relieve the symptoms of most dry-eye patients.

Abstract: An electronic device with a vibrating element which also produces sound includes a casing, an operation panel mounted to the casing, and a vibrator and a processor received in the casing. The operation panel includes a plurality of buttons. Each button can generate an input signal when pressed. The vibrator is attached to an inner surface of the casing. The processor is electrically connected to each button and the vibrator. The processor controls the vibrator to vibrate at a preset frequency in response to the input signal, thereby simultaneously generating sound with the vibration. The size of the electronic device is accordingly decreased.

Abstract: A liquid crystal composition and a liquid crystal display wherein the liquid crystal composition includes: a compound of general formula (I) including 1%-50% of the total weight of the liquid crystal composition; a compound of general formula (II) including 1%-60% of the total weight of the liquid crystal composition; a compound of general formula (III) including 1%-60% of the total weight of the liquid crystal composition; and a compound of general formula (IV) including 0-50% of the total weight of the liquid crystal composition—wherein the liquid crystal composition has a suitably wider nematic phase scope, a suitable optical anisotropy, a favorable low-temperature storage stability a faster response speed, can be used for outdoor work, has a good image display effect, and substantially free of streaking phenomenon.

Abstract: The present invention provides a printed circuit board (PCB) board, a core for manufacturing the PCB board and a method for manufacturing the PCB board. The PCB board is in a shape of a rectangle and comprises a fiber layer formed of interlacedly weaved fiberglasses, a metal layer affixed onto a surface of the fiber layer, and a pair of differential signal traces formed on the metal layer, wherein extending directions of the fiberglasses lie at acute angles with respect to a length direction of the rectangle, and the pair of differential signal traces extends along a width direction or the length direction of the rectangle. The PCB board can effectively reduce the possibility of the skew distortion during the transmitting process of the differential signal through adjusting the angle between the fiberglasses and the edge of the core without adjusting or redesigning the original circuit layout.
